The formula is 1/2 x ( a + b ) x h
A and b are the top and bottom sides and h is always the perpendicular height.

Now replace the variables...
1/2 x (6 + 14 ) x 8.4

And then...

1/2 x 20 x 8.4 which will give you 84cm^2

Hope this helps! Anymore questions let me know :)

Please help me with these, find the missing side. Thank yu only if you know

Answer:

7.48m (3s.f.)

Step-by-step explanation:

Let the missing side be x m.

Applying Pythagoras' Theorem,

x² +5²= 9²

x² +25= 81

x²= 81 -25 (-25 on both sides)

x²= 56

$x = \sqrt{56}$

$x = 2 \sqrt{14}$

x= 7.48 (3 s.f.)

∴ The missing side is 7.48 m (3s.f.)
